“…5,7,[15][16][17] Our results are compatible to those recently published by another group, 5,7 who found that a 24-hour IOP variation in healthy young and elderly control subjects and untreated patients with openangle glaucoma was similar in the fellow eyes. The authors also found that despite a similar overall IOP profiles between the fellow eyes, there was only moderate association between a pair of OD and OS IOP readings at a single time point and this association was worse in glaucoma patients compared with control subjects.…”

“…IOP values are not constant dur ing the day, and IOP fluctuations could lead to misdiagnosis and influence the progress of the disease. Numerous researchers have evaluated the diurnal IOP variation and fluctuation in healthy subjects and glaucoma patients [1,11,22,24]. In some studies [7,9,27,30], IOP had been found to be high in the morning and low in the afternoon and evening, while others [28,29] had shown significantly higher IOP during the dark sleep period in young individuals and in older glaucoma patients.…”

“…Treatment should include the reduction of IOP as well as the reduction of the risks of pressure peaks and elevated IOP fluctuation (1,(6)(7)(8)(9)(10)(11) . To estimate this fluctuation, it is possible to use methods such as the daily tensional curve (DTC), the simplified daily tensional curve (SDTC), and the water drinking test (WDT).…”

Approved by the Research Ethics Committee on human beings with the process number 106/06. RESUMO Objetivo: Comparar a flutuação da pressão intraocular (PIO) nas posições sentada e supina, através da curva tensional diária simplificada (CTDS), durante o horário de consultório em pacientes saudáveis e com glaucoma primário de ângulo aberto (GPAA Descritores: Glaucoma de ângulo aberto/fisiopatologia; Pressão intraocular/fi sio logia; Ritmo circadiano ABSTRACTPurpose: To compare intraocular pressure (IOP) using the simplified daily tensional curve (SDTC) between supine and sitting positions in terms of peak levels and amount of fluctuation in both, glaucomatous and healthy subjects. The secondary endpoint was the comparison of these measures with those derived from the water drinking test (WDT). Methods: Thirty patients with primary open-angle glaucoma (POAG) that were undergoing medical therapy and 30 healthy subjects were enrolled in this study. Each patient underwent a diurnal curve between 8 am and 4 pm. After lying down for 5 minutes, the IOP was measured with the Perkins tonometer. Patients were instructed to sit in the upright position for 5 minutes and the tonometry was repeated. At 4:15 pm, the WDT test was performed. Fluctuation was defined as the difference between the highest and the lowest IOP readings (range). The Student's t test was used to assess differences and a P value <0.05 was considered to be statistically significant. Results: The diurnal curve in the supine position demonstrated higher IOP average values (on average 3-4 mmHg higher) compared to the sitting position (p<0.0001) for both groups. IOP peaks were higher in the supine position; however, the IOP range was essentially the same between the three methods. Treated glaucomatous patients had higher IOP levels in all measurements, but the fluctuation for all tests performed appeared to be similar to that of healthy patients. Conclusion:The data suggested that WDT can be used to estimate the diurnal IOP peak and fluctuation observed in the SDTC of the supine position for treated glaucomatous patients. Further studies can compare the possible correlation between the WDT results and those obtained from nocturnal supine measurements.
